image: During the Ordovician period, the concentration of CO2 in the earth's atmosphere was about eight times higher than today. It has been hard to explain why the climate cooled and why the ...

Hebrew University experts continue in footsteps of researcher who built special reactor that flushes CO2, seawater through ...

For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such ...

A study published in Nature Geoscience reports new findings on the effects that erosion has on the carbon cycle. The study comes from a group of researchers led by Aaron Bufe and Niels Hovius of the ...

The Earth’s natural geological weathering cycle – in which rocks erode and make their way to the sea – traps CO2. But that can take millions of years. Scientists want to accelerate the process to ...

Introduction Have you ever visited a canyon or cave and wondered how those formations came to be? Or observed smooth stones by a river or beach? These results are due to a process called weathering.
